The game was adjudicated a win. And you could force a mate but beyond 50 moves.

This is what happens when you have rules to adjudicate games, and not let the programs play out the moves.

As a tester I never adjudicate games for this reason.

But TCEC is not testing engines. They are running a entertainment tournament. So they have rules to shorten games, dubious openings to force more decisive games etc.etc. This is done to draw people to the site to watch the games.

This is just the nature of the beast. I would not get to bent out of shape about this. All the programs are playing under the same TCEC adjudication rules._________________Professing themselves to be wise, they became fools,
